A. Introduction

A.1. Authorization

Braun Intertec Corporation received authorization from Derek Spitzer of Ulteig to conduct an

Environmental Investigation of the Medina Upper Lagoon Site (denoted as sludge pond or pond) located

at Medina Rest Area near Medina, North Dakota (Site) in accordance with the scope of services described

in our proposal dated March 9, 2016. The Phase II Environmental Investigation was prepared in

association the decommissioning of the Site.

This Phase II Environmental Investigation was prepared on behalf of and for use by Ulteig, the North

Dakota Department of Transportation (NDDOT), the North Dakota Department of Health (NDDH) and the

Federal Highway Administration (FHWA) in accordance with the contract between Ulteig and Braun

Intertec. No other party has a right to rely on the contents of this Phase II Environmental Investigation

without the written authorization of Braun Intertec.

A.2. Project Objective

The objective of the Phase II Environmental Investigation was to characterize the sludge and surface

water, submit for test and prepare the Site for decommissioning in accordance with 40 Code of Federal

Regulations (CFR) 503

B. Site Background

B.1. Site Location and Description

The Site is located at the Medina Rest Area, West of Medina North Dakota. (Figure 1). The Site is located

within southeast quarter of the northwest quarter of Section 7, Township 139 North, Range 69 West, 6.5

miles west of the city of Medina, Stutsman County, North Dakota.

The Site is bordered on the north by a slough followed by United States Highway 94 on the south,

followed by a slough on the east, followed by a field on the west. Beyond the slough to the east is Stink

Lake. A Site Location Map is included as Figure 1.

Derek Spitzer Project B1602950 August 1, 2016 Page 2

B.2. Physical Setting

B.2.a. Topography

According to the United States Geological Survey (USGS) 7.5-minute topographic map series, Medina SW,

North Dakota quadrangle, the Site is located at an elevation of approximately 1750 ft (feet) above mean

sea level.

B.2.b. Geology

The surficial geology of the area consists of collapse glacial sediment with hummocky topography draped

over and partly obliterating the topography that existed prior to the glacial advance (Clayton, 1980). The

glacial till sediments consist of silty-clays and sands deposited by subglacial processes, up to 200 feet in

thickness (Anderson, 2007).

C. Scope of Services

The following tasks were conducted at the Site as part of this Environmental Investigation:

Site Evaluation;

Sampling and Laboratory Analysis;

Project Management.

C.1. Deviations from Work Plan

Because the location of the samples are in a sludge pond we could not use DPT (direct push technology)

to collect these samples.

D. Investigation Methods and Procedures

The fieldwork relating to the investigation was conducted on May 2, 2016. Additional PPE (Personal

Protective Equipment) was used in order to collect the sludge samples. Chest waders underneath a full

body Tyvek© suit was worn to safely collect the samples inside the sludge pond, without coming into

physical contact with the water. The sludge samples were collected via the use of a split spoon sampler

advanced by hand.

Sludge borings SL-1 through SL-5 were collected in the sludge pond.

Surface water samples WT-1 and WT-2 were taken in the sludge pond.


The sludge and surface water sample locations are shown on Figure 2. Standard operating procedures (SOPs) used during the investigation are provided in Appendix A.

D.1. Sludge Evaluation

D.1.a. Sludge borings

Braun Intertec advanced 5 sludge borings, designated as SL-1 thru SL-5 at the Site from inside the sludge

pond to 6 inches below the solid surface.

D.1.b. Sludge Chemical Analyses

Each sample was collected inside the sludge pond approximately 4 ft from the shore. These samples

were taken in a perimeter loop, using a hand driven split spoon.

Nitrate using United States Environmental Protection Agency (EPA) Method 353.2.

Ammonia using United States Environmental Protection Agency (EPA) Method 350.1.

Paint filter test.

Mercury using United States Environmental Protection Agency (EPA) Method 245.1.

Metals using EPA Method 6010.

Resource Conservation and Recovery Act (RCRA) Metals EPA Method 200.8.

Total Kjeldahl Nitrogen (TKN) using Method PAI–DK01.

Total Solids using Method SM2540-G.

Fecal Coliform using Method 9221E.

E. Sludge Evaluation

In order to determine the volume of sludge within the bottom of the pond, thickness of sludge was

determined at five locations within the pond. The thickness was determined from wading into the pond

and advancing a split spoon sampler into the bottom materials until the base of the pond was

encountered. The split spoon sampler was opened, exposing the sludge core for measurement. Based

on the measurement locations, the sludge thicknesses ranged between 5.9 and 6.3 inches, with an

average thickness of 6.14 inches (Figure 2). Given the area of the pond of 4,354 square feet, determined

from air photo, and the sludge thickness, the volume of sludge is estimated at 2,286 cubic feet

(approximately 85 cubic yards).

The total solids of the sludge was evaluated using EPA method 2540 G for determining total solids in solid

and semisolid samples from lake sediments and materials from a wastewater treatment process. The

total solids from the samples ranged from 0.625 and 0.794 grams per gram with an average of 0.729

grams per gram (Table 1). The average total solids of the samples tested is approximately 73%.


F. Investigation Results

F.1. Sludge Analytical Testing Results

Chemical components detected in sludge samples can be compared with their respective Regional

Screening Level (RSL) derived by the Environmental Protection Agency (EPA). A summary of the

analytical results for the sludge samples is provided in Table 1. The results of the laboratory analysis

indicated that:

Fecal Coliform, Nitrate, and Mercury were not detected at concentrations greater than or equal to the laboratory method reporting limits.

Varying concentrations of ammonia and metals were detected in the sludge samples. However, none of the concentrations detected in the sludge samples exceeded their respective EPA RSL.

The complete laboratory reports with chain of custody forms is attached in Appendix B.

F.2. Surface Water Analytical Testing Results

Chemical components detected in surface water samples can be compared with their respective drinking

water Maximum Concentration Level (MCL) derived by the EPA. A summary of the analytical results for

the surface water samples is provided in Table 2. The results of the laboratory analysis indicate that:

Nitrate, Barium, Copper, Molybdenum, Nickel, Zink, Cadmium, Chromium, Selenium, Silver, and Mercury were not detected at concentrations greater than or equal to the laboratory method reporting limits.

Arsenic was reported at concentrations slightly exceeding the drinking water EPA MCL standard.

Varying concentrations of Lead, E. Coli, Coliform, and Ammonia were detected in the surface water samples. However, none of the concentrations detected from the surface water samples exceeded their respective EPA MCL.

The complete laboratory report with chain of custody forms is attached in Appendix B.


F.3. Quality Assurance/Quality Control

Samples were placed in clean, laboratory supplied containers, preserved, labeled, and transported to the

Minnesota Valley Testing Laboratory under refrigerated conditions using chain-of-custody procedures.

Analyses were performed using EPA or other recognized standard procedures. Data were reviewed prior

to release, quality-control guidelines were generally met, and the data is considered usable. Specific

information on standard operating procedures, detection limits, and quality-control measures is available

upon request.

G. Conclusions

For this Phase II Environmental Investigation five sludge and two surface water samples were taken.

These samples were submitted to lab for analysis. The chemical analysis of sludge samples collected did

not show any concentrations above EPA RSLs. Arsenic detected from the surface water was reported at

concentrations slightly exceeding the drinking water EPA MCL. No other compounds or parameters from

the surface water samples showed concentrations exceeding the EPA MCL.

H. Recommendations

Based on the results of this investigation, we provide the following recommendations:

As the only detection above regulatory limits for either sludge or surface water was arsenic, encountered within the surface water at levels that exceed the drinking water standard, we recommend that no further sampling or testing be performed.


I. Investigation Limitations

The analyses and conclusions submitted in this report are based on our field observations and the results

of laboratory chemical analyses of sludge samples and surface water samples collected from the sludge

borings completed for this project.

In performing its services, Braun Intertec used that degree of care and skill ordinarily exercised under

similar circumstances by reputable members of its profession currently practicing in the same locality.

No warranty, express or implied, is made.

SOP 101 – Field Notes and Documentation Page 1 of 5

A. Purpose

The objective of this Standard Operating Procedure (SOP) is to establish a consistent method and format for the use and control of documentation generated during field activities. Field notes, records, and photographs are intended to provide sufficient information that can be used to recreate the field activities and collection of environmental data. The information placed in these documents and/or records should be factual, detailed, and free of personal opinions.

A.1. Scope and Applicability

This SOP is applicable to Phase I Environmental Site Assessments (ESAs), Phase II ESAs, remedial investigations, and Response Action Plan (RAP) implementation. Documentation includes Field Report Form, additional field forms that are part of method SOPs, and photographs.

A.2. Personnel Responsibilities

The project manager (or designee) is responsible for properly preparing field personnel to perform the field work and to oversee that field documentation is collected in accordance with this SOP, site-specific or project-specific planning documents, and other applicable SOPs.

Field personnel are responsible for understanding and implementing this SOP during field activities, as well as completing appropriate Field Report Form to properly document the field activities. Field observations should be discussed with the project manager on a daily basis. If conditions change from initial expectations, a call should also be made to the project manager. Field personnel should document field activities and record field measurements as they occur and complete documentation prior to leaving the site. Field personnel are responsible for tracking the location of field documentation. Field personnel are responsible for preserving original documentation until it is provided to the project manager and placed into the permanent file or archived. Field personnel are responsible for distributing copies (or electronically preserving copies) of the documentation in a timely manner.

E. Procedure

This SOP primarily addresses documentation using the Field Report Form (see Attachment A) or field logbook. However, procedures discussed in this SOP are applicable to other types of field documentation collected. Other field records and forms (e.g., soil boring logs, Chain-of-Custody records, water sample collection records, soil vapor monitoring forms) are discussed in the specific SOP associated with that particular activity and are not described in this SOP.

E.1. Field Report Form

Field personnel will keep accurate written records of their daily activities in chronological order on a Field Report Form that will be sufficient to recreate the project field activities without reliance on memory. Entries should be legible and written in black, waterproof or indelible ink. Each page should be numbered sequentially, dated, and signed by the field author. There should be no blank lines on a page. If only part of a page is used, the remainder of the page should have an “X” drawn over it. The completion of each day’s work and the end of the field project should be clearly indicated with “END DAY” or “END FIELD INVESTIGATION.”

If pre-printed adhesive labels or other added information are glued or taped onto a Field Report Form, the note taker should sign the addition. The signature should begin on the addition and extend onto the Field Report Form page so that the addition cannot be removed without detection.

At a minimum the following information should be recorded for each project:

§ Site/project name § Site location § Site project number § Name of project manager § Full name of Field Report Form author § Names of other Braun Intertec personnel on site and their role (full name and initials) § Name of subcontractors performing work for Braun Intertec (or whose work Braun Intertec is

monitoring) and the full name and phone number of their site superintendent

At a minimum, the following information should be recorded each day:

§ Date § Purpose of the day’s activities § Pertinent weather conditions (temperature, precipitation events, wind direction and speed, general

air quality, particularly any ambient odors). Significant weather changes during the day should be noted

§ Full name and initials of Field Report Form author, if different from previous day § Full name and initials of other Braun Intertec personnel on site and their role, if different from

previous day § Documentation of exclusion zone setup and decontamination procedures, if applicable § Record safety related monitoring information, including the time and location of the measurements or

observations § If not Level D, record the Personal Protective Equipment (PPE) level in which work is conducted and

change in levels and the reason for the change




08/21/2015 01/22/2016

Rev.:

§ Names, phone numbers, and affiliation of all site visitors and their reason for visiting, as well as their time of arrival(s) and departure(s). The project manager should be notified immediately if regulators (e.g., Minnesota Pollution Control Agency [MPCA], Environmental Protection Agency [EPA], Occupational Safety & Health Administration [OSHA]) visit the site. [Note: “all site visitors” means those who are inspecting or observing our work or the work we are overseeing. It is not intended to include unrelated site activities or personnel.]

§ Persons contacted, name, and reason for contact, and decisions made. If the person contacted is not Braun Intertec personnel, also record the phone number.

E.2. Environmental Media Sampling Data

The information below should be recorded on specific forms if they are required by the data collection method SOP, but use of the form should be documented on the Field Report Form. The following information should be recorded:

§ A chronological description of field observations and sampling events (i.e., date and time) § Sampling locations (referenced/scaled drawings or global positioning system [GPS] coordinates, if not

logged) should be identified. The project manager should provide the sample nomenclature system to the field personnel for consistency and continuity on sites with multiple rounds of data collection.

§ Specific data associated with sample acquisition (e.g., field parameter measurements, field screening data, and HASP monitoring data)

§ Source of samples, matrix, sample identification, sample container types and preservatives (including ice), field quality assurance/quality control sample collection, preparation, and origin

§ Conditions that could adversely impact samples, such as smoke, wind, rain, or dust § Make, model, and serial number of field instruments should be recorded in the Field Report Form or in

a separate calibration log along with calibration data § Deviations from the work plan and/or SOPs § Sketches or scaled diagrams § Process diagrams § Waste generated and management methods (i.e., investigation derived waste [IDW]).

E.3. Sketches and Scaled Diagrams

Draw a site map using accurate measurements or make notes on a photocopy of an existing site map. The site map should include:

§ Site boundaries (or features such as street curbs, fence lines etc. that can later be related to site boundaries)

§ Street names or other references that can be related to a site location map § Investigation and well locations with dimensions to site landmarks § Major structures with dimensions § North arrow § Scale § Date § Initials of field personnel

E.4. Photographs

Subject

Photographs should be taken to document existing conditions pertinent to the subject evaluation or remediation at a project site. Except when specifically required, it is unnecessary to photograph processes that are described by SOPs, but rather photograph the results of the process.

Composition

The three most common mistakes to avoid in providing photographic documentation are (1) too few photographs, (2) poor quality photographs, and (3) lack of subject identification in photographs. Photographic documentation should tell the story with as little need for narrative as possible.

When photographing several similar subjects or details that are not necessarily well identified in an establishing shot, such as a test excavations or test excavation spoil piles, it is recommended that you place a clip board with an identifying description in at least the first in the sequence of photographs of that subject or detail.

Scale

Where there are insufficient objects of widely known scale in a photograph, one should be placed in the photograph to provide scale. Some examples include a coin, ruler, clipboard, or cell phone.

Photographic Log

The following information should be recorded in the Field Report Form or field logbook:

§ Site name, location, and field task § Name of photographer § Date and time the photograph was taken (verify the date/time stamp is correct if using a digital

camera) § Sequential number of the photograph § Brief description of the subject of the photograph § Site plan or site sketch showing the location from which the photograph was taken and the direction

the photographer was facing.

E.5. Additional Field Forms/Records

Additional field records may be required for some field events. As an example, these may include soil boring logs during drilling, well construction and development records, groundwater purge and sample collection records, water level measurement records, instrument calibration records, sample container labels, sample container security tags and seals, Chain-of-Custody forms, field equipment calibration and maintenance logs and commercial shipping manifests. Use of these records described in the SOPs associated with the particular activity.

Prior to beginning field activities, field personnel will coordinate with the project manager, or designee, to determine which SOPs will be used and identify additional field forms that are required. These additional records will be maintained in a field file throughout the duration of the field activities. Copies of the records will be forwarded to the project manager (or designee) on a daily basis, if practical to do so.

E.6. Corrections

If an error is made in an entry in the field records, corrections will be made by drawing a SINGLE straight line through the error, entering the correct information, initialing, and dating the change. Materials that obliterate the original information, such as correction fluids, tapes or markers are prohibited. If the reason for the change is not obvious, provide a brief explanation.

E.7. Data and Records Management

Field records should be forwarded to the project manager or designated staff on a daily basis, if practical. The project manager should review progress and results in detail on a daily basis and evaluate the quality of the documentation. The field personnel should scan the field records and place them in the project folder in OnBase. This preserves documentation in the event that the Field Report Form is lost, stolen, or damaged. Copies of the field notes should be maintained in accordance with the Braun Intertec Records Retention Policy and Procedures. Photographs should be uploaded to the EnCon DRAFTS project folder as soon as possible.

Individual logbooks may be assigned to large projects. These logbooks will be returned to the project manager at the completion of field work and archived with the project file. Logbooks assigned to individual personnel for recording multiple project information from multiple projects should be provided to the designated EnCon project assistant for archiving when the logbooks are filled. Each logbook should have a table of contents (TOC) and be kept up to date by the personnel to which the book is assigned.

The TOC for each logbook should list the project names and locations, project numbers, inclusive dates and logbook page numbers.

E.8. Quality Assurance/Quality Control

All personnel that perform field work will be trained in the use of this SOP. Project managers or project staff who use the field notes for interpreting data and preparing reports should provide immediate feedback to those recording field information to reinforce conformance with the SOP and correct deficiencies. Periodic random audits of all field personnel documentation will be performed by the quality assurance (QA) manager or designees.

SOP 208 – Soil Grab Sample Collection Page 1 of 6

A. Purpose

The following Standard Operating Procedure (SOP) for the collection of grab soil samples is intended to be used by Braun Intertec field personnel for the purposes of soil sample collection. Grab sampling techniques should always be used to collect samples for volatile organic compounds (VOC), gasoline range organics (GRO), diesel range organics (DRO) or other analyses that require collection of a generally undisturbed portion of soil. Grab sampling techniques may also be used to collect other analytes such as semi-volatile organic compounds (SVOCs), polychlorinated biphenyls (PCBs), and metals. Grab samples should be collected prior to collection of other sample aliquots as soon as possible after the sampling interval is retrieved. Soil samples collected in the field during investigations for characterization and/or documentation of site conditions are integral to the services provided to clients and regulatory agencies.

This SOP is applicable for soil samples collected from soil borings (SOP 203 – Soil Boring Observation and Sampling), test pits and test trenches (SOP 211 – Test Pit and Test Trench Observation and Sampling), stockpiles (SOP 210 – Soil Stockpile Sampling), and/or excavations.


Field work should be performed in accordance with the Braun Intertec Corporate Health and Safety Manual Standard Operating Procedures and the site-specific health and safety plan (HASP), if applicable.

The following table provides details regarding analytical parameters and the type of laboratory-supplied containers and applicable preservative.

Analytical Parameter (holding time) Bottle Type and Preservation Type

DRO (10 days)* 4-oz. glass jar, pre-weighed and unpreserved 8 RCRA Metals or 13 Priority Pollutant Metals (6 Months, except mercury 28 days)

4-oz. glass jar, unpreserved

GRO (14 days)** 40-milliliter (mL) glass vial, with 10 mL methanol pre-weighed PCBs (14 days)*** 4-oz. glass jar unpreserved SVOCs (14 days)**** 4-oz. glass jar unpreserved VOCs (14 days)** 40-mL glass vial, with 10 mL methanol, pre-weighed

*DRO soil samples collected in 60-mL pre-weighed containers must be filled with 25 to 35 grams or soil. **VOC and GRO soil samples collected in 40-mL pre-weighed containers should contain between 8 to 11 grams of soil. ***PCBs – Polychlorinated Biphenyls ****SVOCs – Semi-volatile Organic Compounds

All soil samples must have a single unpreserved sample collected (5-10 gram minimum) for dry weight analysis (i.e., moisture sample).

E. Procedure

E.1. Bottle Order

Several days before field work is scheduled to begin contact the laboratory to order sample containers and soil coring devices by phone or email. It may be a good idea to order extra bottles to allow for breakage, extra samples, etc. If you are unsure of the required sample volumes or proper laboratory sample containers for specific analytical parameters, ask that a written description be included with the bottle order which clarifies sample requirements.

Upon receipt of the sample coolers and before you leave for the field, check the contents of the cooler to be sure that you have the appropriate sample containers and that extra containers are included, if requested. Be sure you are aware of sample volume and container requirements.

E.2. Cooler Preparation

Place ice or a frozen cold pack into each sample cooler before collecting any samples. Double-bag the ice in sealable gallon bags or sealed garbage bags to avoid potential contact of water in the cooler with sample containers.

Place a temperature blank into each cooler and under the sealed bags of ice. If the cooler will contain VOCs samples ensure that a trip blank is placed into the cooler with the samples.

E.3. Labeling Sample Containers

Prior to collecting soil grab samples, complete the sample label for the laboratory-supplied containers. The sample label must have the following information:

§ Project Number (listed under “Client”) § Sample Name (listed under “Sample ID”) § Date Sample Collected (listed under “Collection Date”) § Sampler’s Initials (listed under “Collected by”) § Time Sample Collected (listed under “Time”)

Additionally, some laboratory-supplied sample containers (e.g., DRO, GRO, and VOCs) have been pre-weighed by the laboratory. It is important to make sure that the pre-weighed sample containers have their weight listed on the sample label and that the weight is visible.

E.4. Soil Sampling

Select sample location/interval per the Work/Sampling Plan. Don new disposable gloves and scrape off a layer of soil to expose a fresh surface. Follow procedures listed below for each specific parameter.

E.5. Volatile Organic Compounds/Gasoline Range Organics Soil Grab Sample Collection

§ Place an electronic scale that has been calibrated that day prior to use on a flat surface. § Turn on the electronic scale. § Before filling the first jar, verify the accuracy of the scale. Place a pre-weighed sample container on

the scale. Compare the reading to the weight on the container. If within 5 grams, the scale can be used for the rest of the day. If not within 5 grams, remove the container, turn the scale off, then on, and repeat the test. If still not within 5 grams, use a different scale.

§ Remove cap from pre-weighed, pre-preserved 40-milliliter (mL) sample vial. § Place 40-mL vial on electronic scale and press “tare” button to zero electronic scale. § Electronic scale should read 0.0g – leave sample vial on electronic scale. § Use the lab provided Terra Core® sampler (5- or 10-gram) or 10-mL syringe with the top cut off

(approximately 10 grams when full) for collecting a sample. The laboratory may provide a different sampling device than described above; whichever device is provided, the goal is to have 8 to 11 grams of soil in the sample jar for VOC/GRO analysis.

§ Scrape off upper layer of soil to expose underlying soil. Remove the syringe cap and push the syringe into the freshly exposed soil until the soil column entering the syringe has forced the top of the plunger to the stopping point against the top of the syringe cradle.

§ Wipe all debris from the outside of the syringe and remove any soil that extends outside the mouth of the syringe, so the soil sample is flush with the mouth of the syringe.

§ Carefully place the mouth of the syringe against the top of the open 40-mL vial and gently extrude the sample into the vial. (Note: to prevent the methanol preservative from splashing out of the bottle, hold the syringe against the top of the vial until the sample has fallen into the preservative.) Try to avoid getting soil on the threads of the vial. Clean the threads if necessary and cap the vial immediately.

§ Weigh the sample bottle. Tolerances and field actions required are presented in the table below:

Actual Sample Weight Volume of Methanol Field Action

< 8 grams 10 mLs Add soil to reach 10 grams 8 – 11 grams 10 mLs None required

> 11 to < 20 grams 10 mLs None required. Laboratory will add methanol to reach 1:1 ratio 20 or > grams 10 mLs Discard bottle and resample

§ Cap the sample container. Gently swirl, do not shake, sample vial to fully immerse soil into methanol. § Fill out the label on the vial completely, including project number, sample I.D., date, time and

sampler’s initials. Record the information on the Chain-of-Custody form and in the field notebook. § Collect at least two vials of soil sample for each analysis (VOCs or GRO). Therefore, if the work plan

requires only VOCs then you will fill two vials; if the work plan calls for VOCs and GRO you will fill four vials (two vials for each analyte).

§ Manually fill a plastic snap-top tube (or similar unpreserved bottle) with soil from the same sampling interval/matrix as each sample. Remove soil particles from the rim of the snap tube so the cap will close securely and close the cap. This jar is for moisture calculation to be submitted with VOCs/GRO soil sample containers and should be labeled the same as the VOC/GRO sample jars. All soil samples for VOCs or GRO analysis require an accompanying moisture calculation jar. Only one moisture jar is required per soil sample (i.e., one moisture jar is sufficient for both VOCs and GRO analysis).

§ Place a trip blank into the cooler with the VOCs/GRO samples; see SOP 308 – Trip Blanks. § Store, transport, and maintain sample custody per SOP 602 – Chain-of-Custody Procedures.

E.6. Diesel Range Organics Soil Grab Sample Collection

§ Place a calibrated electronic scale on a flat surface. § Turn on the electronic scale. § Before filling the first jar, verify the accuracy of the scale. Place a pre-weighed sample container on

the scale. Compare the reading to the weight on the container. If within 5 grams, the scale can be used for the rest of the day. If not within 5 grams, remove the container, turn the scale off, then on, and repeat the test. If still not within 5 grams, use a different scale.

§ Remove cap from pre-weighed, unpreserved sample container. § Place empty DRO bottle on electronic scale and press “tare” button to zero electronic scale. § Electronic scale should read 0.0g – leave DRO bottle on electronic scale. § Use the laboratory provided coring device such as a Terra Core® sampler (5- or 10-gram) or 10-mL

syringe with the top cut off (approximately 10 grams when full) for collecting a sample. The laboratory may provide a different coring device than described above; whichever coring device is provided, the goal is to have 25 to 35 grams of soil in a 4-oz. sample jar for the Wisconsin DRO method and Environmental Protection Agency (EPA) Method 8015, Total Petroleum Hydrocarbon (50 to 70 grams in an 8-oz. jar).

§ Scrape off upper layer of soil to expose underlying soil. Push the coring device into the freshly exposed soil until the soil column entering the coring device has filled to the top of the plunger (Terra Core) or the 10-mL line (cut off Syringe).

§ Wipe all debris from the outside of the coring device and remove any soil that extends outside the mouth of the coring device, so the soil sample is flush with the mouth of the coring device.

§ Extrude soil sample from the coring device into the DRO bottle. Collected soil sample should have a cumulative weight between 25 and 35 grams (4-oz. jar). Repeat the steps above as necessary to achieve necessary soil sample weight. If more than 35 grams of soil are collected, discard all the soil in

sample jar and recollect the sample. Try to avoid getting soil on the threads of the sample jar. Clean the threads if necessary and cap the sample jar immediately after sample collection.

§ Repeat the above steps to fill a second DRO sample container. Two soil sample jars may be required for this analytical method.

§ Fill one unpreserved sample container (typically a small plastic jar provided by the lab) with soil from the same sampling interval/matrix as each sample. This jar is for moisture calculation to be submitted with DRO soil sample containers and should be labeled the same as the DRO sample jars. All soil samples for DRO analysis require an accompanying moisture calculation jar.

E.7. Metals Soil Grab Sample Collection

§ One open-top, 4- or 8-oz. unpreserved jar. § Using a clean stainless-steel spoon, scoopula, or gloved hand, thoroughly mix or homogenize the

interval to be sampled, and fill the unpreserved sample containers with the collected soil sample. Avoid filling the sample containers with gravel or rocks.

§ Wipe soil from the container threads. Close the flip-top of the unpreserved sample container. § Note: if several analyses are being performed for a single soil sample, the collection and submission of

one moisture calculation jar is sufficient for all of the analyses for that one soil sample.

E.8. PCBs/SVOCs Soil Grab Sample Collection

§ Open 4-oz., unpreserved sample container. § Using a clean stainless-steel spoon, scoopula, or gloved hand, thoroughly mix or homogenize the

interval to be sampled, and fill the unpreserved sample containers with the collected soil sample. Try to fill the sample containers with soil and not gravel or rocks.

§ Wipe soil from the container threads. Reseal the 4-oz. sample container with the lid. § Note: if several analyses are being performed for a single soil sample, the collection and submission of

one moisture calculation jar is sufficient for all of the analyses for that one soil sample.

E.9. Alternative En Core® Sampling Method for Volatile Sample Aliquots

An En Core® Sampler (sampler) is a single-use sampling device that allows the collection of a soil sample directly into the sampler. The sampler containing the soil sample is delivered to the analytical laboratory without chemically preserving the sample in the field. An En Core® T-Handle (T-handle) is used with the sampler obtain the soil sample. For VOC sample aliquots, a 5-gram sampler will be used to collect soil samples, and typically three 5-gram samplers will be submitted to the laboratory from each sample interval.

The following procedure is used to collect a soil sample using the sampler and T-handle.

§ Prior to collecting a soil sample, hold the coring body on the sampler and push the plunger rod down until the small o-ring rests against tabs. This will assure that the plunger moves freely.

§ Depress the locking level on the En Core T-handle. Place the sampler, plunger end first, into the open end of T-handle, aligning the two slots on the coring body with the two locking pins in the T-handle. Twist the coring body clockwise to lock the pins in the slots. Check to ensure the sampler is locked in place and ready for use.

§ Turn the T-handle with the “T” up and the coring body of the sampler down. This positions the plunger bottom flush with the bottom of the coring body. Using the T-handle, push the sampler into soil until coring body is completely full. When full, the small o-ring will be centered in the T-handle viewing hole. Remove the sampler from the soil and wipe excess soil from the coring body exterior.

§ Cap the coring body while it is still on the T-handle. Push the cap over flat area of the ridge. Push and twist the cap to lock the arm in place. The cap must be seated to seal the sampler.

§ Remove the capped sampler by depressing the locking level on the T-handle while twisting and pulling the sampler from the T-handle.

§ Lock the plunger by rotating the extended plunger rod fully counter-clockwise until the wings rest firmly against the tabs.

§ Attach the completed label to the cap on the coring body of the sampler. § Return the full sampler to the zipper bag. Seal the bag and place the bag on ice. Samples must be

delivered to the laboratory within 48 hours of sample collection.

E.10. Sample Delivery

Arrange for pick-up/drop off of soil samples in laboratory-provided coolers to the analytical laboratory. If shipping of soil samples to the analytical laboratory is required, follow SOP 603 – Sample Shipping.


Soil samples collected in the field should be recorded in the field report form or field logbook (see SOP 101 – Field Notes and Documentation), on the field log, soil boring log, test trench log, etc., and on the COC (see SOP 602 – Chain-of-Custody Procedures). Information recorded in the field report form or field logbook and on the COC should be identical to the information listed on the sample container label(s). Additionally, it is useful to note how many soil sample containers were filled for each uniquely identified soil grab sample.

Note the presence of any pieces of bituminous in the samples, no matter how small, particularly in samples to be analyzed for DRO or SVOCs.


Quality assurance/quality control (QA/QC) procedures described in the work plan should be followed.

SOP 602 – Chain-of-Custody Procedures Page 1 of 3

Purpose

The purpose of the Chain-of-Custody (COC) Standard Operating Procedure (SOP) is to control environmental samples from the time they are collected until custody of the samples is accepted by the laboratory sample custodian. COC documentation serves three main purposes:

§ Communicates the analytical instructions from the sampler to the analytical laboratory. § Provides a permanent record of samples provided to the laboratory. § Documents that samples were handled only by authorized personnel and were not available for

tampering prior to analysis.

Scope and Applicability

Although few environmental samples will ever be used in criminal or civil litigation cases, most samples are collected in support of government-regulated activities. In addition, it is possible that the results of the sample analyses will be used in future litigation even if none was contemplated at the time the samples were collected. Therefore, it is important that a record of sample possession (i.e., COC) be maintained, so that control of the samples from the time of collection to the time of sample laboratory check-in can be demonstrated.

Laboratory-related sample control is described in laboratory operating and quality-control documents and is not discussed in this standard operating procedure (SOP).

This procedure should be used for control of environmental samples that include, but are not limited to those of groundwater (see SOP 311 – Groundwater Sample Collection), surface water (see SOP 314 – Surface Water Sampling), soil (see SOP 208 – Soil Grab Sample Collection and SOP 209 – Soil Composite Sample Collection), air (see SOP 402 – Indoor Air Sampling), soil vapor (see SOP 403 – Soil Vapor Sampling from a Borehole and with a Hand Probe and SOP 405 – Sub-Slab Soil Vapor Sampling), and waste.

Summary of Method

Environmental samples are collected using methods specified in the work plan or other SOPs. The samples are collected in sampling containers for the desired analyses, preserved as appropriate, and a label is affixed to each container specifying the project name and number, sample identification, date and time of collection, and sample collector. The information is entered onto the COC Form and the desired analyses are indicated on the form, which also serves as the analytical request. Sample custody (possession) is maintained individually until the samples are delivered to the laboratory sample check-in. Transfer of custody is documented on the COC Form by printed name, signature, date and time.

Personnel Qualifications and Responsibilities

The sampler is responsible for understanding, implementing and documenting activities related to this SOP during field activities. The sampler is responsible for transmitting a copy of field notes that have not been forwarded to the project manager or designee, as well as a copy of the COC Form(s) immediately after sample check-in. If there is more than one sampler, the lead field sampler assumes these responsibilities.

Procedure

General Guidelines

§ Keep the number of people involved in collecting and handling samples and data to a minimum. § Only personnel associated with the project should handle samples and data. § Always document the transfer of samples and data from one person to another on the COC Form. § Always accompany samples and data with the COC Form. § Samples should be uniquely identified, legibly, in permanent ink. § Fill out the COC Form as completely as possible. The sample identification information on the sample

containers must match the COC Form. § Use a separate COC Form for each cooler.

Completing CCO Form

The COC Form should be filled out by the sampler or designee as the samples are being collected and containerized.

Securing Samples

If you cannot maintain personal possession of the samples prior to sample check-in, they may be secured. A locked vehicle is considered controlled access (i.e., secured). A cooler sitting on the tailgate of a pickup truck or under an unlocked topper, out of direct view of the custodian is not secure. An unsecured cooler in a locked hotel room is also not within controlled access as hotel staff have access to the room. In this case, the cooler could be padlocked or custody seals could be used to secure the samples or cooler.

Data and Records Management

The original COC Form is maintained by the laboratory in accordance with their file retention guidance. A copy of the record should be provided to the project manager or designee with a copy of the sampling field notes by the sampler immediately after sample check-in.

Quality Assurance Quality Control


The project manager or designee should review the COC Form as soon as possible after sample check-in to verify that the information on the COC Form is correct.

E. Procedure

E.1. General Guidelines

§ Sample containers should be placed inside of sealable plastic bags to reduce the potential for cross contamination, breakage, and melted ice getting into the samples.

§ The drain plug on the cooler, if present, should be taped shut from the inside and outside. § A layer of protective material such as bubble wrap should be placed in the bottom of the cooler.

E.2. Cooler Guidelines

§ If possible, place all contents of the cooler into a large plastic bag that is tied or taped shut to avoid melted ice from leaking out of the cooler during shipping.

§ Sample containers should be placed upright in the cooler, and protective material such as bubble wrap should be placed around the sample containers. Do not stack glass containers or lay them on their side, as doing so increases the chance of them breaking.

§ Fill the cooler no more than 50 percent with sample containers. Fill all the remaining void space in the cooler with protective material and ice to avoid breakage during transport. At least 1/3 of total cooler space should be taken up by ice. When in doubt, use more ice.

§ Ice that is double bagged in sealable plastic bags should be distributed over the top of the samples. § Additional protective material should then be added to the cooler. § Ensure that a temperature blank bottle and trip blank (if needed) is in each cooler and included on the

COC Form.

E.3. COC Guidelines

§ The sampler should relinquish the samples by signing and indicating the date and time that the samples were relinquished to the shipper. The shipping company agent is not required to sign the COC Form.

§ Field personnel should retain a copy of the COC Form and attach it to the field notes. § The COC Form should be placed in a sealable plastic bag and taped to the inside of the cooler lid. At

least one COC Form should be placed in each cooler that is sent to the laboratory.

E.4. Custody Seal Guidelines

§ Close the top of the cooler and rotate/shake the cooler to verify that the contents are packed so that they do not move. Add additional protective material if needed and reclose.

§ Place one custody seal on the front and on the back of the cooler in such a way that the opening of the cooler will destroy the seal.

§ Tape the cooler shut with clear packing tape, wrapping all the way around each end. Be sure to tape over the custody seals.

E.5. Shipping Guidelines

§ Samples sent by private carrier (UPS, FedEx, etc.) will be accompanied by a bill of lading or other shipping document. Shipping documentation should be saved as part of the permanent record. DOT, USPS, and FAA shipping/labeling regulations must be followed. The contents should be described on the shipping documents. Fill out the correct shipping paperwork with the correct shipping address for the laboratory and tape to the top of the cooler, and wrap packing tape around the entire cooler. Retain copies of all shipment records as provided by the shipper.

§ The cooler should be shipped to “Laboratory Sample Receiving” marked “Deliver to addressee only,” and the laboratory should be notified of its approximate delivery date and time.

§ Deliver the cooler or have the cooler picked up by an overnight carrier that guarantees 24-hour delivery. Consideration should be given to the expected delivery date and the weather.


The original request for COC Form is maintained by the laboratory in accordance with their file retention guidance. A copy of the record should be provided to the project manager or designee with a copy of the sampling field notes by the field personnel immediately after sample check-in.

E.7. Quality Assurance Quality Control


The project manager or designee should review the COC Form as soon as possible after sample check-in to verify that the information on the COC Form is correct.

SOP 701 – Decontamination of Sampling Equipment Page 1 of 3

A. Purpose

The purpose of the Standard Operating Procedure (SOP) is the procedure of decontaminating reusable equipment involved in soil, groundwater, and soil vapor activities. Reusable equipment must be properly decontaminated to provide chemical analysis results which are reflective of the actual concentrations present at sampling locations, and to minimize the potential for cross-contamination between sampling locations and the transfer of contamination off-site.

Applicable soil SOPs include SOP 203 – Soil Boring Observation and Sampling, SOP 208 – Soil Grab Sample Collection, SOP 209 – Soil Composite Sample Collection, SOP 210 – Soil Stockpile Sampling, and SOP 211 – Test Pit and Test Trench Observation and Sampling.

Applicable water SOPs include SOP 301 – Water Level Measurement, SOP 302 – LNAPL Level Measurement, SOP 303 – Monitoring Well Development, SOP 304 – Slug Testing, SOP 309 – Field Filtering of Groundwater Samples, SOP 310 – Monitoring Well and Piezometer Installation, SOP 311 – Groundwater Sample Collection, SOP 312 – Well Purging and Stabilization, SOP 314 – Surface Water Sampling, and SOP 316 – Calibration of Water Meters.

The applicable soil vapor SOP includes SOP 405 – Sub-Slab Soil Vapor Sampling.

Be sure to follow the site-specific sampling plan that may require special cleaning or rinsing methods, and/or special handling and disposal of wash and rinse water (also see SOP 702 – Management of Investigation Derived Waste). Additional rinses with solvents such as hexane, acetone, or acid may be required by the site-specific sampling plan, but are not covered in this SOP.



Nitrile gloves should be worn during decontamination activities to reduce the incidence of skin contact with potentially contaminated soil/groundwater and to reduce the risk of cross-contamination. In certain situations, long-sleeved rubber gloves may be needed to prevent contact.

The product interface probe is only used in wells that may contain light non-aqueous phase liquid (LNAPL). Prior to each use the product interface probe should be cleaned as follows:

§ After fluid levels in each well are measured, wipe the probe and tape with a paper towel. § After returning to the office, clean the probe and tape in a solution of phosphate-free detergent and

tap water. Allow the probe and tape to soak in the solution up to 24 hours, if possible.

E.4. Vapor Sampling Equipment

E.4.a. Vapor Pins® – Used for Sub-Slab Soil Gas Sampling

This office-only procedure applies solely to the Vapor Pin® itself that will be used to obtain a soil gas sample. Once the Vapor Pin® has been used it will be brought back to the office and cleaned as follows:

§ Remove the silicone sleeve and discard. § Wash the Vapor Pin® in a hot water and phosphate-free detergent wash. § Bake in an oven to a temperature of 130°C (266°F) for at least one hour.


Observations should be documented in accordance with SOP 101 – Field Notes and Documentation.
